Case Discussion

Calcinosis universalis is a condition characterized by long bands or sheets of symmetrical subcutaneous calcification.

~1/3 of cases are associated with sclerodermadermatomyositis, polymyositis, and systemic lupus erythematosus.

Calcinosis universalis manifests as long bands of symmetrical subcutaneous calcification seen extending along deep fascial planes. Tendon and ligamental involvement has been described.

Unlike tumoral calcinosis, it is plaque or sheet like rather than mass like.
